Notes from LARP-PS2 meeting 5-Feb-09.

Present: A. Fisher, M. Furman, R. de Maria, Y. Papaphilippou, J. Qiang,
C. Rivetta, R. Ryne, J. Smith, P. Spentzouris, L. Vorobjov, UW.

Yannis presented the "frozen" PS2 lattice & reviewed its parameters. A
copy of his talk will be on this Indico page once I get it. A
MADX file is now available on the PS2 Wiki (thanks, Riccardo). The
address is https://twiki.cern.ch/twiki/bin/view/Main/PS2Collaboration
Note that there are some changes since HB2008. The Wiki page clearly
separates between the current lattice and older versions. Note that
the current version does not have chromaticity sextupoles, these are
maybe 2 weeks away.

The space-charge group needs a lattice description with
beam lines rather than sequences, Yannis thought he could provide
that without undue effort. 

We discussed CM12 briefly. Dates are April 8-10. I expect PS2 to have
a half-day session. In part because of the higher funding requested
for FY2010 we need to make a good case (not that I think that would be
too difficult!).

Robert & Panagiotis indicated that they expect to have some results by
CM12. Depends of course on difficulties in reading in the
lattice. They are ready to roll.

Miguel is looking into e-cloud build-up in the dipoles and expects to
have results for CM12 as well.

Claudio needs more input before they can start looking at
(multibunch-) instabilities. (He may start by using the parameters of the new
MI cavity (once they become known) that Fermilab is presently
designing).
